The LED light source characteristic of solar street lamp has:1 、 high luminous efficiency, small power consumption, long service life and low working temperature.2 、 safe and reliable.3, the reaction speed is quick, the unit volume is small, green environmental protection.4, the same brightness, the power consumption is 1/10 of incandescent lamp, fluorescent lamp 1/3, and the service life is 50 times that of incandescent lamp, fluorescent lamp 20 times, is the fourth generation lighting products following the incandescent lamp, fluorescent lamp, gas discharge lamp.
Q:Is the LED courtyard lamp cold?
LED is afraid of the heat, the heat is not good, directly lead to decay,
Q:Introduction to garden lamp components
Fluorescent lamp, energy-saving lamp is a low pressure mercury vapor arc discharge lamp, usually long, at each end of an electrode. The lamp contains mercury vapor with low pressure and a small amount of inert gas, and the inner surface of the tube is coated with phosphor powder. Fluorescent lamps are divided into straight tube fluorescent lamps and compact fluorescent lamps. Straight tube fluorescent lamp according to the starting mode can be divided into preheating start, fast start and instantaneous start several, according to the tube can be divided into T12, T8, T5 several. Compact fluorescent lamps are developed for use in power hungry incandescent lamps with low energy consumption and long life. Ordinary incandescent lamp life is only 1000 hours, compact fluorescent lamp typical life of 8000-10000 hours.
Q:Consult the advantages and disadvantages of the metal halide lamp and the LED miner's lamp
1, energy saving. 2, long life. 3, the applicability is good, because a single LED is small in size and can be made into any shape. 4, the response time is short, the NS (nanosecond) level of response time, while the ordinary luminaire is the MS (millisecond) level of response time. 5, environmental protection, no harmful metals, waste easily recycled. 6, brilliant color, light color pure, narrow spectral range, and through the red green and blue three primary colors mixed into colorful color or white. Disadvantages: 1, the price is expensive. 2, there is still a big gap between luminous efficiency and theoretical light efficiency. 3, there is still a big gap between the current life and the theoretical life (10W hours). 4, there is still a certain amount of fever. 5, can greatly reduce the light attenuation.
Q:How much ballast does the LED 15W lamp belt need?
15W light belt, the ratio of 15W-20W constant current switching power supply on it
Q:How to determine the power of LED street light?
If the LED street lamp is a block of chip, it can be installed according to the height and brightness of the street lamp, and then it can be estimated that each block is 30W/50/100W
Q:What does the "40WP" in the technical parameters of the solar LED courtyard lamp mean?
The unit of output power of solar cells in standard sunlight. The European Commission defines the 101 standard, the radiation intensity 1000W/m2, the atmospheric mass AM1.5, the battery temperature 25 degrees, the output power of solar cells.
Q:How to configure solar garden lamps?
Following solar LED lighting market trends analysis: 1. solar LED lighting presents the following three characteristics: the rapid decline in prices, domestic installation growth slowed down significantly, and the rapid growth of the export market. Of course, there must be a cause, and the emergence of this phenomenon has a certain relationship with all aspects. First, to further enhance the LED technology, LED outdoor lighting problems of functional heat dissipation, attenuation, power and other problems being solved. At the same time, the rapid decline in upstream chip prices, LED outdoor functional lighting products to enhance the performance price ratio. Secondly, the government promotes LED outdoor functional lighting products to speed up the promotion. Governments all hope to realize energy conservation and emission reduction by installing LED street lamps and LED courtyard lights, while achieving good social benefits.
Q:Yard light installation manual fee
Solar street lamps use 12V power supply, it is not easy to cause electric shock, and ordinary street lamp adopts 220V voltage. Once leakage or short circuit occurs, it may cause casualties.
Q:What is the usual height of garden lights?
2.5 meters -5 meters, usually about 3.5 meters, much production, but also relatively symmetrical, beautiful.
